To el? .ark/ mi it may concern y y Bc it knovfn that Walitiiiisoi It. EWELL .and in'i'iitii D Soiirns, citizens ot' the United States, residing at New York city, New York, and Bristol, Connecticut, respectively, have invented certain neiv and useful Improvements in Resetting Counters, of which the following is a clear, full, and exact description.

This invention relates to counters such as used for recording the number ot' revolutions ot' a shaft or the number of movements of a. reciprocating part.

rEhe invention is particularly4 applicablev to a counter having ar number of dials of different denominations. geneiallyheld behind 'a case and as each counted increment occurs, the dials are sutiniciently rotated or advanced to bring the numbers of the dials successivelyvbefore the sight openings or windows. To securefaccuracy ot indicated result by preventing undesired movementsuch as through an overthrow, counters ot this type are lusuallyy provided With means for holding the dials against rotation when they are not being advanced in a counted or added movenient. lV-hile vthe invention is particularly useful in counters, the invention is appli cable to calculating machines of various constructions. it is necessary at times to reset the' dials to zero.

in object of this invention is to provide a very vsimple mechanism for normally locking the dials against rotation for the purpose stated above, and at the same tiineto provide inipro'vednieans tor resetting the dials to Zero ivhen desired.

A desired object of the invent-ionis to enablejthe accomplishment of the above re-y sults Withoutin any Way interfering with tlie"transferring devices which transfer or carry from the dialsof lower denomination-tolthe dials ofthe next higher denoini` nation.

Further objects of the invention Will Vappear hereinafter. y

Windows not illustrated, through Whichfff numbers upon the dials 9, 9??, 99,. 9d and dem. may be seen. These dials are preterablyar ranged in a. slightly inclined position so th their edges overlap in order to save space 'and lthe spindles 10 of the dials, are corre-' spondingly inclined and parallel iwith each invention these spindles l0 are oftnbular '.ff torni so that each spindle presents a bore 10it j in which there is mounted a depressible pin 11, the outer end of which preferably; pro- 8p jects and presents'a rounded nose 12. vThe-'v'` ends of the spindles 10 are rotatably mount ed in the forward Wall 8. ofthe caseand'iin, .i the back Wall 8a. Each spindle provid lf with a rigid pallet Wheel 12 and a a transfer Wheel 13 Whichmay be adjacentlto the Wheel 12. Each transfer Wheelispr vided with a pin llt which, once in every re olution, engagesone often notches 1,5 int'li pallet wheel of the next higher denomination .l

so as to transfer or carry when `the 'nuinbe responding Pallet Wheel 19 'Se ,este ,sans tutiai transfer device orI carryingldfevic" f ,error si 'en 'is T vided with 10. shallow concave/note When the carrying or transferjinove not taking place, a shiftable'collar' vory 17 on the spindle of the next lowerl d nationA .holds its corresponding trans-t Wheel .against rotation `as 'illustrated inV Fig. 4. Each of the small -vizheels Tor-.collars has a concave notch or recess 18 which will lie adjacent to the edge of the interlocking transfer wheel at the moment that the carrying movement takes place so as to permit the rotation of the transfer through one space. As the dials are rigid on the spindles 10, it is obvious that the dials are (except 'when carrying) locked against rotation. lVe provide means for enabling the wheels 13 and 17 to -be disengaged wlienthe dials are to be reset to zero. In order to accomplish this, we prefer to arrange the wheel 17 to slide on their spindles, -and'hold each wheel '17 in its normal position by means of a spring 19 within the tubular spindle and thrusting inwardly against a transverse pin 20 which passes diametrically across wheel 17 and through a sloti21. These wheels 17 may all be shifted simultaneously by means of a cani bar 22 arranged to slide longitudinally at the rear WallS, said cam bar being provided with inclined or cam faces 23 which engage the noses 12 of the pins 11, so as to depress the 'pins when the 'bar is shifted. This bar may be shifted in any suitablemanner suchlas by means of a bell-crank lever 24, and the cam bar maybe guided so as to slide longitudinally between pins 25.

In order to hold the cam bar 22 normally in the positionshown in 1, we may provide a spring 26 arranged to thrust 'against a bearing for the shaft 28, the revolutions of which are to be counted. This shaft 28 may advance the units Adial 9 by means of a radial pin 29 carried on a rigid collar 30. Below this collar 30 there is provided a longitudinal shiftable collar 31 to perform' a function similar to the wheels-17, that is, it normally interlocks with the units transfer wheel but is provided with a notch 32 in its edge which is opposite to the pin 29 so that when the pin 29 engages the units pallet wheel the'rota-` tion 'of the units dial is permitted. The collar 31 has a rigid disk or flange 33 which enables the collar 31 to be depressed by means of two pins 34 similar to the pins 11, and actuated by cam toes 35 on a fork 36 formed on the end of the cam bar 22. A coaxial spring 35a holds the collar 31 in its normal position. It is understood that each wheel 13 cooperating with its interlocking mate constitutes a locking couple for normally locking all the dials against rotation, except inthe carrying movement. The cam -bar 22 is preferably held under a cover plate 36 fastened on the back of the' case, sliding on lugs 36a.

"Wh-en the cam bar 22 is shifted as suggesteri, all the-pins 11 will be forced forwardly and their inner ends thrusting against the cross pins 20 will evidently shift all o'f the wheels 17 longitudinally on their -sspmdles and disengage them fromtheirv wheel 13 corresponding interlocking wheels 13. At the same time the pins 34 will thrust forwardly against the disk or flange 33 and disengage the collar 31. The dials may then be all reset simultaneously to zero provided Awheel is preferably provided on its side face with a circumferential bent spring pawl 38. One end of each of these spring pawls may oe attached as 'at 39 in Fig. 5', and the other end project so as to lie in the path of piu 40 which is carried by each of the spindles. Vhen the dials are being advanced in the counting movement, the pins 40pass around in a direction so that they will slide along the faceof each corresponding spring pawl and thrust it to theI side without aifect- Amg the gears, but when Athe gears are rotated, the ends 41 of these spring pawls come against the pins 40 so as to pickup the spindles, which become drivenmembers in the resetting mechanism, and the-se spindles are connected with the dials in some manner so as to rotate them; the dials may be rigid on the spindles if desired, but this is not essential s 'o long as the rotation of the driven resetting member in the direction to resetwill cause the rotation of the dial.

It will be seen that the driven connection between the driving-members and the driven members is a one-way drive connection, that is the rotary movement can be transmitted only in one direction. The gear wheel 37e which corresponds 4to the dial 9e of highest denomination is loose with respect to its spindle 10. It is fixedto an inner shaft 42 which extends through the forward end of the spindle of the dial 9e and which may be slotted to receive a removable key. The gear wheel 37e may be fixed to the inner shaft 42 as shown in Fig. 6. It will be evident that when the wheels 13 and 17 are released from each other, the dials may be rotated in unison by rotating the shaft 42,

the direction of rotation of the dials vbeing indicated by the arrows shown adjacent to their respective spindl-es. Each of the pins 40, is in a predetermined position with respectI to the zero on the face of the corresponding dial, and the gears are arranged derstood that we do not restrict ourselves to the form of the invention described, nor consider ourselves limited to this construction in our claims.
